Context values
Some unit families need one extra value for a physically accurate result.
Milliampere is 0.001 ampere units.
Result = input x 1e-6 / 0.001.

About Converting Microamperes to Milliamperes
Microampere and Milliampere both belong to the electricity family — voltage, current, resistance, power, or energy — units that show up constantly when working across the different standards used by household wiring (120V/240V depending on region), automotive electrical systems (12V/24V), and electronics design. Specifically: Microampere is 0.000001 ampere units, and milliampere is 0.001 ampere units.
Formula
milliamperes = microamperes × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 microampere equals 0.000001 base units, and 1 milliampere equals 0.001 base units, so dividing one by the other gives the direct microampere-to-milliampere factor of 0.001.
Simple example
1 uA × 0.001 = 0.001 mA
1 microampere = 0.001 milliamperes.
Real-world example
120 uA × 0.001 = 0.12 mA
120 microamperes = 0.12 milliamperes.

Reverse conversion: Milliampere to Microampere
0.001 mA × 1000 = 1 uA
0.001 milliamperes = 1 microampere.
microamperes = milliamperes × 1000

Frequently asked questions
How many milliamperes are in 1 microampere?
1 microampere equals 0.001 milliamperes, using the exact defined conversion factor rather than an estimate.
How do I convert microampere to milliampere?
Multiply the microampere value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert milliampere back to microampere?
Use the reverse factor: 1 milliampere equals 1,000 microamperes. You can also use the swap control in the converter above to flip the direction instantly.
What is a microampere?
Microampere (uA) is a unit of electricity.
What is a milliampere?
Milliampere (mA) is a unit of electricity.
Is the microampere to milliampere conversion exact?
Yes. Both microampere and milliampere are defined by fixed standards rather than physical artifacts, so the factor of 0.001 used above is exact to as many digits as you choose to display.
What's the difference between voltage, current, and resistance?
Voltage (volts) is the electrical potential difference driving current through a circuit. Current (amperes) is the rate of flow of electric charge. Resistance (ohms) is how much a component opposes that flow. They're related by Ohm's law (V = I × R), but they are distinct physical quantities, and this page converts between units of just one of them.
